Boxwoods

We have several boxwoods in our foundation plantings. We recently noticed a few branches were turning brown and seemed to be dying. We pruned back a few of these branches and noticed a white substance on the branches. I sprayed with Sevin as I suspected an insect infestation. The infested boxwoods may have to be replaced. The boxwoods are about 10 years old. I would like to save the rest of them, if possible. Any help you can provide will be appreciated. I have included photos. Thank you.

I had a soil test done that indicates a need for phosphorus, and recommends 22 lbs./1000 sq ft. of triple superphosphate (0-46-0). This seems like a lot given that the application rate per 1000 sq ft on the bag is 1 Lb. Thoughts???

Hello! I'm writing to you about several otto luyken laurel shrubs in my yard...

Hello! I'm writing to you about several otto luyken laurel shrubs in my yard that are planted side by side to create a hedge. They are roughly 5 feet tall and are approximately 8-9 years old. Many of the trunks and branches are covered in a white mildewy looking powder. The leaves on these branches are yellowing, dying, have some holes in them,and are falling off. This happened last summer too and I ended up having to cut out the affected branches leaving some pretty big wholes in the shrubs. Nobody I asked at my local garden centers seemed to know what it was or how I should treat. It's starting to happen again this year. The shrubs grow pretty much in full sun, but there are no soil or drainage problems that I know of. If you could please help me figure out what to do and how to treat them? They're a beautiful hedge right in front of my house and to lose them would be devastating!!! Thank you so much; I would sincerely appreciate your advice. Kim Thompson kathompson8@gmail.com

Animal hole

We found this large hole next to our house foundation. We noticed the white foam pieces as well and are wondering what we should do.

Chestnut oaks are dying

Many of the chestnut oaks in a wooded section of our yard are dying. We have one large mature oak whose leaves turned brown quickly and are dropping. I noticed a few weeks ago that a sapling next to our driveway did the same thing. Upon further investigation it seems that several saplings have died and it appears that several other mature trees are also affected. These trees have leaves that have wilted but are not yet dead. I am in Harford County. There are no pesticides, herbicides, or fertilizers used near the trees. Some of the affected trees are located next to our driveway. Is there a known disease affecting Chestnut oaks?

Tree identification

I'd like your help in identifying this tree thanks. It is growing rather prolifically along the wooded edge of this property. Leaves are serrated and grow in odd numbers groups of 3,5, or 7 depending on maturity Bark on the branches and newer growth is quite smooth, but bark on the trunk is fairly rough Thanks as always for your help

imidacloprid se

I have cherry laurels as a privacy screen (approx. 8.5 ft. tall). 2 have heavy infestation of White Prunicola Scale. My research indicates treatment with a soil drench of imidacloprid. My confusion comes from the directions on the 1 gal. container. It says use the height of the shrub (in rounded feet - up or down) times 3 to equal the amount of product to use (in oz). I have 7 of the cherry laurels in a row. Looking at just 1 @ 8 ft high (with heavy infestation) times 3 = 24 oz. (In a gallon of water). Here's the problem - in that same instruction for shrubs it states "DO NOT apply more than 9.4 oz a.i. imidacloprid per 1000 sq. ft " Given this restriction I would be 14.6 oz over the limit for just the one shrub. What is the correct amount of product/gallon to use? How do I address the other 6 cherry laurels in the same row (2 heavily infested and 1 partially)? I also have horticultural oil to soak the branches.
